Sort based on another sheet values

[naflas]

There are 3 sheets in the attached document. I want to sort sheet 2 based on values in the sheet1 . Once it has got shorted, the values order in the sheet 2 should be same as sheet 1. Additional values that are not in sheet 1,but in sheet 2 should be listed at the end.

In other words the output should be same as in sheet 3.

Please help me on this
